Crash on reload

Hi everyone:

Have any one got a crash when issue reload command from the CLI?

Just wondering if anyone have the same problem with me.
I use cdr_odbc to store my cdr records in mysql database,
and I didn’t load as suggested.
when asterisk start for the first time, there is no problem at all, but if I issue a reload from CLI , I will get a segmentation fault, and asterisk dead.

after some try and error, I figure it out that every time I reload, asterisk will crash.
Is this a bug of ?
How can I make it work?

I am using asterisk 1.2.1

thanks in advance
